Expand `load-suffixes' docstring.
Delete default_suffixes and DEFVAR_LISP the new variable
`load-file-rep-suffixes'.
(x_uncatch_errors): Unused count argument deleted.

(x_uncatch_errors): Deallocate last x_error_message_stack struct.
(x_check_errors): Call x_uncatch_errors before signalling error.

(mac_begin_clip, mac_end_clip): Take arg GC instead of REGION.
All uses changed. Don't do clipping if n_clip_rects is zero.
(mac_set_clip_rectangles): Use xassert instead of abort. Set
n_clip_rects. Don't make clip_region empty when number of
clipping rectangles is zero.
(mac_reset_clip_rectangles): Set n_clip_rects directly instead of
calling mac_set_clip_rectangles.
(x_set_toolkit_scroll_bar_thumb): Temporarily hide scroll bar to
avoid multiple redraws.
BG_WIDTH. All uses changed. Draw background if BG_WIDTH is not zero.
(mac_draw_image_string, mac_draw_image_string_16): New arg BG_WIDTH.
[USE_CG_TEXT_DRAWING] (mac_draw_image_string_cg): Rename from
mac_draw_string_cg. New arg BG_WIDTH. All uses changed. Draw
background if BG_WIDTH is not zero. Use float constants as
divisors instead of double. Use alloca instead of xmalloc/xfree.
(x_draw_glyph_string_background, x_draw_glyph_string_foreground)
[!MAC_OS8 || USE_ATSUI]: Background may be drawn using
mac_draw_image_string* functions.
(XLoadQueryFont) [MAC_OS8 && USE_ATSUI]: Don't adjust heights of
some fonts when srcCopy text transfer mode might be used.
(mac_begin_clip, mac_end_clip): Check if region is empty.
(mac_set_clip_rectangles): When resetting clip region, make it
empty instead of disposing of it.
